Error

Question
What I don't understand is why the $JAVA_HOME is incorrect ? (should be /var/jenkins_home/tools/hudson.model.JDK/Java_10/jdk-10.0.2, no ?)
I've try to set it on the global properties of the jenkins system configuration, but I've get the same output/error (and don't want to set it here as there can be other java_home for other java installation)
What am I missing ?

EDIT Opened an issue to Jenkins (Jira - JENKINS-54959)

EDIT 2
After some discussion with the Jenkins crews, we finally found the missing option. As the archive contains a subdirectory (here jdk-10.0.2), we need to inform the de-zipper with the subdir field

Optional subdirectory of the downloaded and unpacked archive to use as the tool's home directory

so now, I got the error

Solution

  • OK,

    by installing the Java 11 Support Preview is available in Jenkins 2.155+ I'm not anymore having the java error \o/

    I'm closing this problem :)
